Is coal gasification the clean energy of the future?
Coal gasification is looking to be the solution to the pollution problems that have led some of the country to a standstill. Although there are problems; coal gasification actually produces more CO2 than traditional coal plants meaning that China will be using more coal and affecting the environment just as much. The second problem is water use.
